SSL certificate problem (SSL alert number 42)
Hello,
After client (Thunderbird, now version 31.0) updated today, it stopped connecting to Dovecot IMAP4S. The infamous "SSL alert number 42" is reported.
Mail server uses local (created for intranet) CA certificate as root.
I would appreciate pieces of advice on how to handle that without enabling plaintext authentication over insecure channels.
Other intranet services work with

Dovecot IMAPS : Thunderbird SSL cert issue / Evolution OK
Recently thunderbird and Dovecot IMAPS cannot agree on SSL however
Evolution, on the exact same system, is working fine with the same
accounts. Tried recreating the Dovecot cert and also the thunderbird
accounts from scratch. The OpenSSL raw client works fine as well.
Would someone also confirm the openssl commands to create a selfsigned
cert for dovecot imaps. They cert created does work

Dovecot IMAPS : Thunderbird SSL cert issue / Evolution OK
I would expect the public cert to be imported as a "server" not an "auth"
The attached image shows that TBird wants an httpS url for a webserver,
for the source.
Ages ago, I think it prompted for "do you want to trust this new cert"
and YES added it (assuming that is the public key) to the server list.?
A bit confused by this.

Dovecot IMAPS : Thunderbird SSL cert issue / Evolution OK
Hello,
This is a selfsigned cert. Both of the below methods were used.
May I ask for 1. pointer to info setting up "intermediate certs" and
where the certfile goes?
The objective is to generate a self-signed cert and use it for just
internal use with IMAPS dovecot.
Separately, what are your thoughts as to why evolution works and
thunderbird does not?
Thank you,

Upgrade to 2.2.32 from 2.2.15 failed
No, is that something that would make a difference between 2.2.15 and 2.2.32?

STARTTLS problem
Hi,
We try to configure dovecot as usual (all our servers have
dovecot+vpopmail+qmail or postfix).
We set up dovecot with the next outcome:
- imap ok
- imaps ok
- imap STARTTLS NOT OK
Debug:
root at s13:/home/lucas# gnutls-cli --starttls -p 143 ip
Resolving 'ip'...
Connecting to 'ip'...

Cannot Authenticate user with Kerberos/GSSAPI
My last message probably contained too much information. This one is more succient.
I have a user, 'mark', who has been running a Thunderbird client on Windows to Dovecot server
with Kerberos/GSSAPI authentication for over a year. I created a new Tbird account on a new
Linux workstation for 'mark', also with Kerberos/GSSAPI and that worked just fine.

stopped being able to kerberos/GSSAPI authenticate with new email accounts
I've been running with Dovecot 2.2.15 on my mail server and Thunderbird on workstations with
Kerberos/GSSAPI authentication. This has been working for over a year for 10 users.
The other day, I replaced a user's workstation and set up this user with a Thunderbird client.
Unfortunately, I got the error:

Upgrade to 2.2.32 from 2.2.15 failed
I have a problem. I have been running Dovecot 2.2.15 and I'd like to upgrade. My distro
(Slackware) has dovecot 2.2.32 available. I downloaded and installed that, but it didn't work.
No one was able to get messages from the dovecot server on their workstations. The following is
the entire dovecot log file from startup to the last message generated. No more messages went

My dovecot works fine against Active Directory 2003, but not against AD2008
hi,
check your
/etc/openldap/ldap.conf
for
REFERRALS off
I had this errors with "referrals on" in misconfigured dns environments.
you can debug the dns packets by strace-ing the auth process

Apple mail fails with Submission
Hi,
Below, you have only the submission-login debug log (authentication).
I'm more interested in what happens after that. You'll need to enable
mail_debug=yes (at least for the user involved) to get that.
Regards,
Stephan.

SSL Warnings in Debug Logs
Greetings,
In doing some debugging of authentication issues, I'm wondering if these
SSL warnings are anything to be investigating?
